PACKAGE-'ROLLI OF METALLI-C LEAF."

1'0 (//ZfZ whom, it may concern: A'

Be it known that I, WALTER H. COE, a citilen of the United States,residing at Providence, county of Providence, in the State of RhodeIsland, have invented a new and useful Improvement in Package-Rolls ofMetallic Leaf, of which the following is a specification.

In the manufacture of package-rolls of metallic leaf heretofore it hasbeen customary to' apply wax or other adhesive material to one side of apaper strip and a powdered material to the op osite side, whereby themetallic leaf WoundJ up With the su portingstrip may be unwound from theroll without liability of running up on the back of the said stri Iisthe object of my. invention to dispense `with the usel of both adhesiveand non-adhesive materials in connection with the supporting-strip of apackage-roll; and my inveiition consists in a package-roll of metallicleaf in which the sup orting-strip is provided with a smooth surfliceupon one side and comparatively rough surface upon the other side,whereby the metallic leaf will be unequally acted upon by the surface ofthe said stri and the package-roll may be unwound Wit out liability ofdisplacing the fillet of metallic leaf from its pro er connection withthe unwound strip, and tlfie troublesome employment of Wax or powderwill be avoided.

In the accompanying` drawings, Figure 1 re resents a side view of apackage-rollof meta lic leaf, the metallic leaf being indicated by thebroken line.- Fig. 2 represents an enlarged section of a portion of theoutspread paper strip and the metallic leaf.

In the drawings, A represents the spirally- Wound package-roll, thesupporting-strip c of which is made smooth on the side b, which is atthe outer side of the roll, and com aratively rough at the side c, uponWhic the metallic leaf d is'cleposited. The-metallic leaf when unwoundfrom the package-roll A will be properly held on the said supportingstriby the naturai tendencylof the metallic lea to cling to the rough sideand leave the smoothv side thereof.

' By the use of my im rovement'the manufacture of package-rollsimplified and a great saving of time isl effected, both in theirmanufacture and use7 and the rolls so formed are adapted for a varietyof purposes.

The required smooth and rou h surfaces may be imparted to the paper o'which the s of metallic leaf is" strip is formed either in the mill inwhich it isv manufactured or paper of a suitable quality and alike onboth sides may have one of its sides rougliened by passing the' paperbetween pressure-rolls, one of which has a roughened and the other asmoothsurface.

I claim as my invention#v A package-roll of metallic leaf having itssupporting-strip provided with a smooth surface at one side, and acomparatively rou h surface at the other, whereby the metalic leaf maybesuitably lieldfor delivery upon unwinding the roll. f
